Command the Garage and the Road
A dead battery isn’t just an inconvenience—it’s a variable you can control. The RUGGED BY SCHUMACHER SL1668 delivers 1200 peak amps of lithium power, providing the raw strength needed to revive up to 7.0L gas and 4.0L diesel engines. Whether jump starting your vehicle on a cold winter morning or ensuring you’re road-trip ready, this unit is a sleek, high-performance recovery tool.
Specialized Tech for Extreme Conditions
Standard automotive jump starters often fail when the temperature drops, but this unit is engineered for the real world. Featuring integrated pre-heat technology, it warms battery cells to ensure reliable cranking even in freezing climates. For deeply discharged batteries, the pre-boost mode safely adds a preliminary charge. Coupled with a jump start override mode, the SL1668 allows you to successfully jump start vehicles other portable jump starters cannot detect. It also has reverse hook-up protection to prevent damage to the battery and vehicle if the clamps are reversed.
Versatility Beyond the Garage
This is more than a jump box; it’s a 3-in-1 auto essential that keeps digital gear as ready as your vehicle. The high-capacity internal battery functions as a mobile charger, providing multiple recharges for your phone or tablet via the 2.4A USB port. From the roadside to the marine dock, the longer 24-inch booster cables, tough housing, and multi-mode LED light ensure you have the durability, visibility, and power required to handle battery emergencies with precision.
